Abstract


  • The aim of this study was to evaluate the use of the DietAdvice website, a self-administered

    online dietary assessment, in the context of a dietary intervention randomized controlled trial

    [ACTRN 12608000425392]. Data available from a total of n=118 volunteers recruited to the

    dietary trial and using the website in the clinic at t=0, 3 and 12mo was compared with that

    obtained from diet histories (DH) and 3-day food record (FR). Fasting blood samples from

    these time points were also correlated with the macronutrient values obtained. Complete web

    based records were obtained for 65% of participants at t=0, 83% at t=3 and 75% at t=12mo.

    At baseline, values for dietary energy (p=0.01), carbohydrate (p=0.036), saturated (p=0.001)

    and monounsaturated (p=0.014) fat were significantly different for all assessment methods

    while at 3 months only that for energy (p=0.041) was significantly different. Overall stronger

    correlations between the macronutrient values from DietAdvice and blood biomarkers were

    observed at t=12months. In both settings, the data from DietAdvice was most similar to that

    of the 3-d FR . It appears that trial participants had difficulty using DietAdvice website

    independently. Compared with data obtained from the primary healthcare setting the limited

    assistance with the website provided to trial participants may have affected the results.
